In a remarkable convergence of sports engineering and precision bearing technology, JTEKT has successfully adapted ONI BEARING technology—originally developed for high-performance road bicycles—to enhance the efficiency and performance of racing wheelchairs. This innovation not only reduces rotational resistance but also empowers athletes to conserve energy and sustain greater speeds on long distances.
Engineering Challenge
Competitive wheelchair racing presents a unique set of mechanical challenges. Athletes depend on every ounce of efficiency to maintain speed and reduce fatigue. Traditional wheel bearings, while robust, still introduce measurable resistance that can significantly hinder performance—especially during rapid starts and prolonged races. In this demanding environment, lowering rotational torque and rolling resistance becomes mission critical.
Technological Solution: ONI Bearing Integration
JTEKT leveraged its ONI BEARING technology—a solution rooted in years of expertise with bicycle wheel bearings—to address these challenges. Originally designed for road bikes, ONI Bearings optimize rolling characteristics through precise design and materials that drastically reduce frictional forces. Installed in the wheels of racing wheelchairs, these bearings delivered over 30% reduction in rotational torque, a breakthrough that allows athletes to transfer more of their effort into forward motion with less energy loss.
Athlete Impact & Performance Gains
The performance benefits go beyond numbers on a torque meter. By lowering the effort required to initiate wheel rotation and sustain momentum, racers can conserve physical energy—especially crucial over marathon distances. Feedback from trial users highlighted noticeably smoother acceleration and more stable cruise phases, prompting some teams to adopt the bearings on both front and rear wheels for enhanced performance consistency.
Cross-Industry Innovation
This case exemplifies how bearing technology, often unseen yet vital, plays a role far outside traditional industrial applications. By migrating advancements from cycling to adaptive sports equipment, JTEKT showcases how modular bearing innovation can unlock performance gains in diverse applications—pushing both mechanical boundaries and human potential.
Problems
- Athletes have high stress at atart of a race and during riding due to wheel resistance.
- It is very difficult to keep cruising speed.
- Athletes want to minimize the loss of energy as much as possible on the long distance race.
Solutions
- JTEKT now offer newly developed bearings that are using ONI BEARING technology that was specifically designed for road bikes into the wheels of racing wheelchairs!
- JTEKT succeed to reduce more than 30% lower rotational torque by low-friction torque technology. As a result, athletes can save their energy!
